Your answer would be 4x-7=-3(3+4x) because it only has one solution which is x= -1/8
If you sum the amounts of each ingredient, you have a total of
So, the whole cocktail is 50ml. Of these, 10 are coconut milk. So, the ratio coconut : total is
1 - (1/4 + 2*1/4)
1 - 3/4
1/4 of the living room still remains unpainted.
First we need to multiply to make the fractions have equal denominators so we can add/subtract.
math: 1/3 x 4/4=4/12
science: 1/4 x 3/3=3/12
Now we can find the time she spent on history (I assume this is what you are looking for)
Total time-math time<span>-science time=history time</span>
12/12-4/12-3/12
=5/12
Amy spent 5/12 of her time working on history.
3 over 5 x minus 15 = 6 over 5 x plus 12
3/5x - 15 = 6/5x +12
-3/5x+3/5x-15=6/5x-3/5x+12 subtraction property
-15=3/5x+12 simplified
-12-15=3/5x+12-12 subtraction property
-27=3/5x simplified
(5/3)(-27)=3/5 (5/3)x multiplicative inverse
-45=x
